Introduction
Data Preprocessing
The RIXS data was collected at multiple $L$ values along the $(H, K, L)$ direction in reciprocal space. Raw spec files from three measurement sessions (Oct 5, 6, 8, 2023) were converted to JSON format and unified into a single dataset organized by $L$ value.
Each scan entry contains: - Momentum in r.l.u. $(H, K, L)$ - Energy loss spectrum (positive energy = excitations) - Intensity normalized by mirror current - Sample position and angle metadata
The energy axis was inverted during preprocessing to follow the standard RIXS convention where positive energy corresponds to energy loss.
RIXS Spectra
RIXS spectra measured at different $(H, K)$ points for various $L$ values. The spectra are normalized by mirror current and colored by $\sqrt{H^2 + K^2}$ to visualize the momentum dependence.
